10. Steve Martin/Alec Baldwin

It made sense in theory. Why not bring together the two most iconic non-Timberlake "SNL" hosts—one of them a two-time Oscar host, the other an Oscar nominee experiencing a career second act as a sitcom star—especially since Baldwin and Martin had just costarred together in "It's Complicated?" But the result was a mishmash, with Martin's lackadaisical delivery playing awkwardly alongside Baldwin's antic energy. (The "30 Rock" star looked visibly nervous at times.) The ring-a-ding-ding jokes didn't help: ''And over here is the "Inglourious Basterds" section... and over here are the people who made the movie'' Heyoooooo!
